LFF
Lesotho Friends Forever

*Lesotho is a country in Southern Africa, to which many outsiders love the country because of the sincerety of the Basotho people.

**The accronym represents people who are involved on the Lesotho front in order to combat the poverty and the injustices the country has.
Because we both met through the organization, Help Lesotho, and we both have a strong interest in the country of Lesotho; we consider each other: LFF!
